Many stems grow in bundles. The height is 40 to 76 cm, and half of them are inflorescences, so it is a medium to slightly smaller bamboo-leaf. The leaves are slightly spaced at each stem node and have a distinct short petiole. The leaf blades are 10 to 30 cm long, wide needle-shaped, thin, and flat with thin, slightly shiny, and dark green leather. They are very similar to bamboo-leaf leaves. Additionally, it seems unusual that the leaf veins are in a clear lattice pattern, although it is not so conspicuous. The flowering period is from summer to fall, and the stem is extended long, with a few side branches appearing. Elongated spikelets form spikes on each branch. The spikelets have no handle, stand at a large angle with respect to the axis, and all spikelets on one branch protrude in the same direction. Lophatherum gracile has a pointed, almost cylindrical shape and has a sharp acorn shape because of its sharp point. There are a lot of short stings at the tip, and there are many backstabs.
